This code is anti human? This is the standard and the programmer writing habits of serious conflict XML.
XML first in the general data exchange fell to JSON, HTML standard also lost support is very normal.
The invention of x++ so the code, for every knock a letter will hate.

If you don't feel disgust, you code not enough.
